The document provides a detailed case study of Fallingwater, a house designed by Frank Lloyd Wright in 1935, showcasing his philosophy of organic architecture that harmonizes structures with their natural surroundings. Fallingwater is notable for its innovative cantilevered design and incorporation of natural materials, and it has been recognized as a national historic landmark and a significant work of American architecture. It served as a weekend home for the Kaufmann family until it was donated to the Western Pennsylvania Conservancy in 1963 and is now a public museum.
